Holbrookia
''Holbrookia'' is a genus of earless lizards, known commonly as the lesser earless lizards, in the family Phrynosomatidae. The genus contains six recognized species, which are found throughout the Southwestern and Central United States and northern Mexico. They are characterized by having no external ear openings, presumably to prevent soil from entering their bodies when they are digging. Etymology The generic name, ''Holbrookia'', is in honor of American zoologist John Edwards Holbrook. Description Lesser earless lizards grow to about 2.0-2.5 in (50–65 mm) snout-to-vent length, plus a tail of 3–4 in (75–100 mm). They are typically grey or tan in color, with black blotching. The males usually have blue patches on either side of their bellies, whereas the females do not. Females often change to have bright orange patches when gravid. Behavior ''Holbrookia'' species are diurnal, basking lizards. They spend the vast majority of their time sunning on rocks, eve ...

Holbrookia Propinqua
''Holbrookia propinqua'' (keeled earless lizard) is a species of phrynosomatid lizard. Description The dorsal scales are small, pointed, and keeled, as the common name implies.

Geographic range and habitat ''Holbrookia propinqua'' occurs in the Tamaulipan mezquital ecoregion where it is known from various vegetation zones in south Texas, including mixed oak forest, mesquite brush-lands, cleared fields, coastal prairie, and grasslands, although always where bands of Tertiary sand outcrops or sandy stream-side deposits are found. It is perhaps most common in the loose and shifting sands of beaches, barrier islands, and the Coastal Sand Plain of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holbrookia Subcaudalis
''Holbrookia subcaudalis'', commonly known as the southern spot-tailed earless lizard, is a species of lizard in the genus ''Holbrookia''. It was previously considered a subspecies of Holbrookia lacerata. Geographic range It is found in northern Mexico and the United States in southern Texas. Description The southern spot-tailed earless lizard is overall light grayish tan in color, with two paravertebral rows of transverse light-edged dark blotches, one row down either side of the back and a second lateral row of dark, pale-edged blotches that are usually not connected to the paravertebral blotches. Adults are in total length. They have round, dark spots on the ventral surface of the tail, a characteristic which gives them both their common and scientific names. As with all species and subspecies of earless lizard, they have no external ear openings. When gravid, females will often turn greenish yellow on neck and trunk. Behavior As with all earless lizards, the southern spot-t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Holbrookia approximans'', the speckled earless lizard, is a species of earless lizard which is found in the Southwestern United States and northern Mexico. It is sometimes referred to as the western earless lizard. Taxonomy The speckled earless lizard has been elevated to full species status as ''Holbrookia approximans''. Description The speckled earless lizard is an overall gray-brown in color, with black and white speckling all along its back, with a solid gray-brown underside. It has distinct black and white bars immediately preceding the hind legs. Males tend to have a blue coloration to the white bars, whereas females do not. Like all species of earless lizards, it has no external ear openings. Behavior Like all species of earless lizards, the speckled earless lizard is diurnal and insectivorous. It prefers sandy, grassland habitats In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as t ...

Holbrookia Lacerata
''Holbrookia lacerata'', commonly known as the spot-tailed earless lizard, is a species of phrynosomatid lizard. Geographic range It is native to Mexico, in the states of Coahuila, Nuevo León and Tamaulipas, and to the United States, in south-central Texas. Taxonomy Originally described as a species, it was once reclassified as a subspecies of the lesser earless lizard, ''Holbrookia maculata'', but has since been again elevated to full species In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate s ... status. References * Further reading * Boulenger, G.A. 1885.

Earless Lizard
Earless lizards are two genera of small lizards native to the semiarid and grassland habitats of the Southwestern United States and Mexico. The genus ''Cophosaurus'' and the genus ''Holbrookia'' are both characterized by having no external ear openings, presumably to prevent sand from entering their bodies as they dig. Distinctive features Earless lizards typically vary from long. Males tend to be larger than females. The male has two heavy black strips ahead of its hind legs (pictured). The female differs in that she has a black stripe behind each thigh. A pink throat and flanks indicate pregnancy. Earless lizards have two throat folds, large eyes, and 27 or fewer femoral pores. They are also described as having shorter fore legs compared to their hind legs and also rather long toes. Although they are called earless lizards, they are still completely capable of hearing, but their ears do not have an external opening. This feature is useful when they burrow underground withou ...

Phrynosomatidae
The Phrynosomatidae are a diverse family of lizards, sometimes classified as a subfamily (Phrynosomatinae), found from Panama to the extreme south of Canada. Many members of the group are adapted to life in hot, sandy deserts, although the spiny lizards prefer rocky deserts or even relatively moist forest edges, and the short-horned lizard lives in prairie or sagebrush environments. The group includes both egg-laying and viviparous species, with the latter being more common in species living at high elevations. The earliest fossil remains of this group are known from the Late Cretaceous of Mongolia and belong to the genus ''Desertiguana''. As phrynosomatids are presently known only from North America, these remains indicate that phrynosomatids likely had a wider distribution in prehistoric times. Genera The Phrynosomatidae are organised into 9 genera in this family. The earless taxa (''Cophosaurus'' and ''Holbrookia'') are sister genera. Family Phrynosomatidae * ''Callisaurus' ...

John Edwards Holbrook
John Edwards Holbrook (December 31, 1796 – September 8, 1871) was an American zoologist, herpetologist, physician, and naturalist, born in Beaufort, South Carolina, the son of Silas Holbrook, a teacher, and Mary Edwards. Although Holbrook's memoir, written by his medical partner, and his tombstone both give the date 1794 for his birth, this is incorrect. Holbrook received his A.B. degree from Brown University in 1815, and his M.D. from the University of Pennsylvania in 1818. In 1827, he married Harriott Pinckney Rutledge (1802–1863), granddaughter of John Rutledge and a member of the Middleton-Rutledge-Pinckney family. He provided the first comprehensive illustrated account of North American amphibians and reptiles in the two editions of his ''North American Herpetology; or, A Description of the Reptiles Inhabiting the United States''. The first edition in four volumes (1836–1840) is very rare because Holbrook attempted to destroy all copies in a bonfire in his backyard over ...
